The development of construction machinery is an important equipment for the construction of the national economy and plays a pivotal role in the equipment industry. China's construction machinery industry's sales revenue in 2007 was 222.3 billion yuan, ranking second in the world's construction machinery industry. From 2001 to 2007, the average annual growth rate exceeded 24%. The export volume increased from 224 million U.S. dollars in 1998 to 8.7 billion U.S. dollars in 2007, and has increased 37 times in 10 years. China’s construction machinery industry has an important position among the global peers. The products have been exported to Europe and the United States and other engineering machinery powers. "Making a big country" and "manufacturing a strong country" are moving forward. However, compared with the international advanced level, there is still a gap in the overall level of China's construction machinery. Some products are in the position of second- and third-tier products in the international mainstream market; China's construction machinery enterprises are more competitive with large-scale construction machinery multinational enterprise groups. Still weak. In the journey to the construction machinery manufacturing powerhouse, the development situation will be more severe and the challenges will be even greater. The situation is the globalization of the economy and the market, the fierce competition and the individualization and facilitation of demand, the diversification of relevant stakeholders, and the speed of technological development. This requires us to scientifically and accurately predict the future and respond quickly. Only in this way can we maintain the advantages that have been formed and catch up with the advanced. Humanistic care and sustainable development have become the concept of scientific and technological innovation in the industry. As an extension of human capabilities, engineering machinery has been developing together with the progress of human civilization. With the advancement of science and technology, human beings' continuous pursuit of quality of life and attention to dignity have raised many new issues for the development of engineering machinery. China's construction machinery industry responds to the demand and attaches great importance to strengthening the integration and integration between microelectronics technology, information technology, optoelectronic technology, new material technology and machinery manufacturing technology, and promoting product research and innovation in the fields of diversification, intelligence and green. The intelligentization and product specification extension highlights the application space of humane care engineering machinery products. With the increasing demand for quality of life, human beings have gradually expanded from the traditional fields of construction, road construction, water conservancy and electric power, mining to narrow urban construction. Agricultural construction sites in places, hilly areas and in warehouses, docks, warehouses, cabins, farmhouses, gardens, horticulture, building and underground engineering operations, and large-scale, extra-large construction projects and mine expansion. Therefore, engineering machinery is required to gradually extend to both ends, that is, miniaturization, large-scale, and large-scale. With the increasing number of large and extra-large engineering machinery products, the market demand continues to grow. They have the characteristics of long development and production cycle, high technology content and high added value. They represent the manufacturing level of a country or an important enterprise engineering machinery. These products are mostly monopolized by several multinational companies in developed countries. On the other hand, in order to improve production efficiency, reduce labor intensity, improve working conditions, and replace manual labor with mechanical work as a development trend, the demand for small and micro construction machinery will be adapted to the requirements of this engineering environment. Rapid growth. The micro-products are not only subject to specific constraints, but also their appearance, color and other aspects of the design more and more integration with nature and the environment, but also highlights the humanistic care of respect for human nature. Secondly, the same product is developed from a single function to a multi-functional and flexible direction, that is, adding modular functional components based on general-purpose products to achieve diversification of product functions; or through new modular design, manufacturing and different modules. The flexible combination between the two to achieve functional diversification, the traditional division of engineering machinery products will be challenged. The engineering bulldozer should extend to the ends of micro, small and large, extra large and so on, and develop multi-functional, multi-purpose, high-efficiency and energy-saving products and corresponding auxiliary function modules that meet the requirements of different working conditions such as wetlands, deserts and bushes. The loader should develop large-scale environmental protection products with large bucket capacity, large engine power, large excavation force, large dumping load, large traction, and low exhaust emission. It can be loaded, can be grasped, can be unloaded, can be lifted, and economical. A good multi-purpose product (such as a crusher). Engineering excavators should extend the development of large hydraulic excavators, mini excavators, unmanned hydraulic excavators, remotely controlled underwater excavators, underwater bulldozers, and underwater trenchers. The wheeled crane should develop a multi-purpose multi-purpose product with advanced technology, high reliability, long service life, good construction quality and high new technology content. Through the informationization and intelligentization of construction machinery, it can improve the self-diagnosis and repair ability of various failures of construction machinery, reduce the labor intensity of construction workers, improve work efficiency and project quality. Under some special working conditions, such as high temperature, severe cold, high altitude, radiation, underwater and underground conditions, it can replace the construction personnel for intelligent and high quality construction. The application of automation control and remote control of the operating system, precise positioning and control of construction, fault diagnosis and monitoring, etc. on construction machinery will become more and more common. New construction machinery products such as loaders, excavators, road-building machinery, forklifts, concrete mixing and transportation machinery and cranes, which are developed using electromechanical and hydraulic integration technology, electronic computer technology, monitoring and control technology, and integrated technologies of these technologies, will continue to emerge.
